Unless the device you need to power draws very little power and doesn't care
about voltage, you really should get a proper 10/3 100 foot extension cord.
Just
the 50 foot 14/3 is going to have significant losses from end to end.
Ummmmm.... 14ga copper wire has a resistance of 2.58 milliohms per foot, or
129 milliohms in fifty feet. Just how much of a loss do you suppose that's
going to cause?
That would be 258.
VD on a 13A load would be 13 * .258 = 3.35V
